Abstract
Se proporciona un método de decodificación. El método incluye recibir un flujo de bits de video que incluye una unidad de imagen (PU), donde la PU incluye una unidad de capa de abstracción de red (NAL) de encabezado de imagen (PH) que precede a una primera unidad NAL de capa de codificación de video (VCL), y decodificar una imagen codificada de la PU para obtener una imagen decodificada.
